EZ1086CM-3.3TRT-A0

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The EZ1086CM-3.3TRT-A0 is a positive low-dropout linear regulator manufactured by Semtech Corporation, providing a fixed 3.3V output with a maximum current capacity of 1.5A. It utilizes a DDPAK package featuring four pins (three electrical plus tab). The device is engineered for high efficiency, supporting input-to-output differentials as low as 1V. Dropout voltage is specified as a function of load current, guaranteeing performance up to 1.5V at maximum output current. This component serves as a reliable solution for stable voltage regulation in power supply designs requiring precise fixed output levels.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the exact suffix TRT-A0 against official Semtech documentation to confirm tape-and-reel packaging and specific manufacturing lot codes. Ensure the DDPAK pinout matches your PCB footprint design. Cross-reference the part number with authorized distributors to confirm authenticity and avoid counterfeit components. Check for any recent obsolescence notices or lifecycle status updates from the manufacturer before finalizing procurement plans.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3.3V output is required with high current capability. It is suitable for applications where input voltage varies but remains sufficiently above the dropout threshold. Consider the thermal performance of the DDPAK package relative to ambient conditions and heat sinking requirements. Compare against adjustable variants if flexibility in output voltage is needed instead of a fixed setting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the EZ1086 series of low-dropout regulators designed for high-efficiency power management. It shares architectural similarities with other LDOs in the lineup but offers a fixed 3.3V option. The series is known for robust line and load regulation over temperature variations. It complements Semtech's broader portfolio of precision analog and mixed-signal components used in industrial and consumer electronics.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes may include other 3.3V, 1.5A LDOs in compatible packages such as TO-220 or D2PAK. Verify pin compatibility and thermal characteristics carefully. Adjustable versions like the EZ1086AJ require external resistors to set 3.3V. Ensure replacement parts meet the same dropout voltage specifications and current ratings for equivalent performance.
